Answer:
m∠B = 31°
Step-by-step explanation:
First, find the measure of angle ACB by subtracting its supplement from 180 degrees:
180 - 113 = 77
m∠ACB = 77°
Then subtract both m∠A and m∠ACB from 180 degrees, since the interior angles of a triangle always add to 180°:
m∠B = 180° - 72° - 77°
m∠B = 31°
Answer:
7.5 miles
Step-by-step explanation:
Given
- In cycling,He covered 9 miles in
hours,Therefore his avg cycling speed, u
- In second event, It took him
hours to complete,And his avg speed,v is 7
slower than in previous event
⇒v= u-7
v= 12-7
v=5
Distance covered in 1st event
Distance covered in 2nd event
3 less: -3
difference of 16p and 15p: 16p - 15p = p
is equal to: =
the difference of 3 and 1/2: 3 - 1/2 = 2.5
p - 3 = 2.5
Isolate the p. Note the equal sign. What you do to one side, you do to the other. Add 3 to both sides
p - 3 (+3) = 2.5 (+3)
p = 2.5 + 3
p = 5.5
5.5 is your answer for p
hope this helps
First simplify
(x^2+2x+1)-4
x^2+2x-3
Then factor
(x+3)(x-1)=x^2+2x-3
